    The performance of athletes can be affected by respiratory limitations. Studies show that inspiratory muscle training (IMT) could enhance respiratory function and improve exercise performance, impacting energy metabolism. Cyclists, during their activity, may experience fatigue, leading to a sympathetic vasoconstrictor response in the peripheral locomotor muscles, increasing the sensation of dyspnea and the perception of effort, which can result in lower performance. Objective: To determine the effects of an inspiratory muscle training program on physical endurance in amateur cyclists, as well as to evaluate the strength of the inspiratory muscles to develop and apply this program. Materials and Methods: This is an analytical, observational, longitudinal study with a quantitative approach, conducted at the Fipsicocenter Biomedical Center in Ambato. Following inclusion and exclusion criteria, IMT was applied using a Powerbreathe device, with an initial load of 50%. The maximum inspiratory pressure (Pimax) was assessed at the beginning and end of the training to determine the strength of the inspiratory muscles and any changes after the program. To assess physical endurance, an Astrand protocol was used to evaluate oxygen consumption (VO2max). Results: An inspiratory muscle training program offers significant advantages in endurance and performance in cyclists. By enhancing inspiratory capacity, Pimax and VO2max increase, which in turn reduces respiratory muscle fatigue and improves ventilatory efficiency and recovery. Additionally, notable improvements were observed with the use of inspiratory muscle training devices such as Powerbreathe. Conclusions: Inspiratory muscle training has a positive effect on inspiratory muscle strength, increasing Pimax, which leads to improved physical performance and endurance in cyclists. However, there is still a lack of knowledge and application of this type of training in athletes from various disciplines.
